I have added the Microsoft WSE 2.0 SP3 Runtime.msi file into my Setup Prerequisites list through the editor in the Tools menu. Everything seems to work fine and I set Setup Prerequisites Location to extract from Setup.exe option. When I run by installer, it shows the setup prerequisite screen, along with the name of the prerequisite and says click OK to install. Then, a progress bar at the bottom shows up saying extracting Microsoft WSE 2.0 SP3 Runtime.msi, that disappears, and it goes into my normal installer. I checked add/remove programs and WSE is not there. I even checked the normal installation directory for the files that would normally get installed with WSE and they're not there. It looks like it's not installing it for some reason. Verbose logging showed nothing. Please help.
